The role of running in strengthening the cardiovascular system

In this scientific article we are talking about of physiological activity, a significant volume of circulating blood in the human body, approximately 60-80%, is in a state of relative stagnation, being deposited in the capillary network and internal organs. Only a relatively small portion of the total volume, approximately 20-40%, is actively circulating. As the body engages in running, it gradually synchronizes its systems with the established motor rhythm. Gradually, a characteristic subjective state emerges, which can be described as a feeling of inner harmony and "flying," where the effort is transformed into a seamless and fluid movement. Running not only strengthens the body, but also increases the levels of endorphins, known as "happiness hormones." This can help in managing stress, depression, and anxiety.
